Fig. 6 is a view similar to Fig. 1 of a window frame with an outwardly swinging sash and illustrating my invention applied thereto.

Fig. '7 is a view similar to Fig. 6 showing the arrangement of the parts when the sash is in closed position.

For the purpose of illustrating the application of my invention, I have shown in Fig. 1 a window indicated in its entirety at II] which comprises a window frame H constructed with a header it, vertical frame members l9 and a sill 2|. These frame members have a rabbet 12 which is adapted to receive a window sash 13. The sash i3 is constructed in the ordinary manner with rails M and stiles I5 which support a window pane H5 in the customary manner. The sash I3 is hinged to the header ll of the frame II by means of hinges H! which are attached to the upper rail 14 and the header I1 and which permit of the sash swinging from an open position as shown in Fig. 1 to a closed position as shown in Figs. 2 and 4 in which the sash is received within the rabbet l2 and vice versa.

My invention may utilize either one or two sash fasteners which are attached to the stiles 15 of the sash l3 and to the vertical frame members IQ of the frame [0. However, for the sake of simplicity only one sash fastener has been shown which is indicated in its entirety by the reference numeral 22 and which will be described in detail.

The sash fastener 22 as best shown in Fig. 1

. justed, always remains the same.

consists of two arms 23 and 24 of substantially equal length which are hingedly connected together by means of a friction joint 24a and are pivoted at their other ends to the frame II and sash l3 equal distances from the axes of the hinges l8 in a manner to be presently described. When the sash is closed these arms overlie one another and may be swung jointly from the position shown in Fig. 2 to that shown in Fig. 4 and vice versa. When disposed as shown in Fig. 4, the sash is locked by a construction which will be presently described in detail. When the arms are disposed as illustrated in Fig. 1, the window is held in outwardly adjusted position by the friction joint 24a which will now be described in detail.

The arm 23 is preferably constructed of sheet metal and is provided at the end thereof at which the joint 24a is situated with a circular ear 25. Intermediate the ends of this arm and from one of the edges thereof issues a strap 26 which is constructed with a portion 21 best shown in Fig. 3, which is bent at right angles thereto. From this portion issues angularly another portion which is bent at right angles to the first portion and which is adapted to overlie the arm proper the portions 21 and 28 being integral with arm 30. This portion of the strap is provided at its end with an ear 28 which overlies the ear 25 and which is spaced therefrom as shown in Fig. 5. Arm 24 may also be constructed of sheet metal and is provided with an ear 29 identical with the ears 25 and 28 and disposed between the same. Between these various ears are two friction washers 3| and 32 which may be constructed of fiber or some other similar suitable material. A bolt 33 extends completely through all of the ears 25, 29 and 28 and the two washers 3| and 32. This bolt is constructed with a head 34 and a square shoulder 35 adjacent the said head. Shoulder 35 is received in a square hole 36 in the ear 28 and passes freely through a circular hole 31 in the washer 32 which is of a diameter equal to the diagonal dimension of the hole 36. The two ears 25 and 29 are constructed with circular holes 38 and 39 which are of the same diameter as the threaded shank 4| of said bolt. Washer 3| is also constructed with a hole 42 similar to the hole 3'! of washer 32. Bolt 33 includes a nut 43 which is screwed upon the protruding end of the shank 4| thereof and which bears against the ear 25. It will readily be comprehended that the bolt 33 is held from rotation by engagement of the square shoulder 35 with the square hole 36 in ear 28. Since both ears 25 and 2B are integral with arm 23 no turning movement can be imparted to nut 43 by the opening of the arms since the bolt 33 is held from rotation. This prevents unscrewing of the said nut and the pressure on the washers, once the bolt has been ad- In this manner a friction joint is provided having uniform resistance to the opening or closing of the sash and which will not vary in effect excepting as wear occurs. It will readily be apparent that any desired degree of friction may be procured by merely adjusting the nut 43 so that compensation for wear may be readily obtained when the occasion demands. By means of the friction joint 24a the sash may be held in any partially open position or the same may be held in fully open position as desired.

For attaching the sash fastener to the window frame II, a bracket 44 is employed which is constructed of sheet metal and which is bent to provide a base 45 with a flange 46 extending upwardly therefrom. A rivet 41 passes through this flange and the outer end 48 of arm 23 and pivots the said arm to the bracket. Bracket 44 is secured to the frame member I9 of frame H by means of screws 49 which are directly screwed into the face of the said frame member.

The arm 24 is attached to the sash 53 by means of a bracket 5| which is similar to the bracket 44. This bracket is constructed from sheet metal and is bent to provide a base 52 and a flange 53 extending upwardly therefrom. A rivet 54 passes through the flange 53 and the outer end 55 of arm 24 to pivot said arm to the bracket. Bracket 5| is secured to the stile |5 of sash 3 by means of screws 56 which pass through the base 52 and extend into the sash of the stile I5. It will be noted that both of the brackets 5| and 44 are arranged with their bases extending from the flanges in the same direction. This is for the purpose of bringing the joint 24a outwardly of the edge of stile |5 so that the arms may swing to clear the sash when the sash is opened. In order to attach the bracket 5| to the sash, the arm 24 is bent at 5'1 and 58 to cause the end 55 to become offset from the ear 29 forming a part of the friction joint 24a. It will thus be seen that the bolt 33 clears the sash so that the sash may swing from the position shown in Fig. 2 to that shown in Fig. ,l and vice versa without interference.

If the two arms 23 and 24 were in alignment when the sash is in its fully open position, as shown in Fig. 1, it would be impossible to close the sash Without first breaking the joint. To overcome this I construct the ear 29 of arm 24 with an extension or finger 59 which is adapted to engage the portion 21 of strap 26. This finger is so constructed that the arms 23 and 24 when the sash is fully open have such a relation that the same readily fold into closing position when the sash is closed by exerting pressure directly on the sash in the customary manner.

The sash fastener illustrated is adapted to be moved into a position to lock the sash from movement by merely swinging the arms jointly from the position shown in Fig. 2 to that shown in Fig. 4. This is accomplished as follows: In the first instance the two arms are of substantially the same length and the brackets 44 and 5| are so disposed that the axes of the rivets 4'! and 54 are substantially in alignment when the sash is in closing position, as shown in Fig. 2. This permits both arms to be swung jointly or in unison about the same axis. To effect locking, a lug 6| is formed on the arm 24 which is adapted to engage the portion 21 of the strap 26 and to limit the closing movement of the two arms to a position in which the arms are in substantial alignment. When the sash fastener is in the position shown in Fig. 4 any movement of the sash outwardly is resisted by the strap 26 and the lug 6| which in effect forms a lock preventing unintentional opening of the sash.

Where the sash fastener is used on an outwardly swinging sash, the locking feature is dispensed with and the fastener merely used for holding the sash in adjusted position. In Figs. 6 and '7 a sash fastener constructed in accordance with my invention has been illustrated in which most of the parts are identical with those previously described. These parts will not be again described and similar reference numerals preceded by the digit I will be used to designate the corresponding parts.

In the form of the invention shown in Figs. 6 and 7 the bracket 44 is dispensed with and a mounting 62 used in place thereof. This mounting consists of a plate of sheet metal which is constructed with a raised portion 63 and to which the end I55 of arm I24 is pivoted. A rivet 64 serves for this purpose and passes jointly through the parts I55 and 63. The mounting E2 is attached to the lateral surface of the vertical frame member H9 of frame III by means of screws 65. Where the device is to be used in an installation of this type the assembly of the arm I23 with respect to the arm I24 is reversed so that the lug I6I does not come into engagement with the portion I21 of strip I26. However, arm I24 is constructed on the side thereof opposite the lug I6I with another lug 66 which is adapted to engage the portion I21 of strap I26 and which limits closing of the arms I23 and I24 to a position in which said arms are out of alignment. It will be readily apparent that when outward swinging of the sash H3 is initiated that the arm I24 must commence to swing upwardly, since the sash II3 also has an upward component of movement. Were the two arms I23 and I24 in alignment, such movement could not be initiated unless the said arms were manually engaged and swung jointly with the sash. However, by the use of the lug 65 the arms are held out of alignment as shown in Fig. 7, which permits of moving the sash without the necessity of manual swinging of the arms at the same time the sash is opened. The finger I59 the same as in the other form of the invention engages the portion I2! of strap I26 and limits the opening of the arms to the same position as shown in Fig. l. The finger I59 is made symmetrical so that the same operates in identically the same manner whether the parts are assembled in one manner or the other. It is to be noted that the arm I23 is attached to the sash when installed as shown in Figs. Band 7 and to the frame when installed as shown in Fig. 1.

In the installation of my invention with either form of sash the fastener is merely closed as far as the abutments will permit. The same is then inserted at the proper locality where the window and frame adjoin and the parts secured thereto by the screws provided. The device is then ready for operation. It thus will become evident that it is impossible to erroneously install the fastener and once the same has been installed will continue to operate properly.

The advantages of my invention are manifest. By means of the particular construction employed substantially the same fastener may be installed either upon an inwardly opening sash or an outwardly opening sash. The device is practically fool proof both as to installation and operation. With my invention the strap which serves as part of the locking means for the bolt adjustment forms a stop for limiting the movement of the arms. With my invention the fastener is incapable of movement beyond desired extreme positions. In the manufacture of fasteners in accordance with my invention the same dies can be used for both arms, and only a special die required for the mounting attaching the fastener to the inner face of the window frame. My invention is extremely simple in operation and construction and can be built at a nominal cost.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
